php运行脚本，导出excel文件

    $excelObj = new PHPExcel();
    $dir = '/tmp/';

    // 给表格添加数据
    $excelObj->setActiveSheetIndex(0); // 从0开始
    $currentSheet = $excelObj->getActiveSheet(); // 获取当前活动sheet
    $currentSheet->setCellValue( 'A1', 'ID' )         //给表的单元格设置数据
    ->setCellValue( 'B1', '公司全称' )
        ->setCellValue( 'C1', '公司简称' );

    $designObj = DB::table('design_company')->select([
        'id as ID',
        'company_name as 公司全称',
        'company_abbreviation as 公司简称',
    ])->get();

    $new_data = [];
    foreach ($designObj as $k=>$v){
        $arr = [];
        foreach ($v as $a=>$b){
            $arr[$a] = $b;
        }
        $new_data[] = $arr;

    }

    $j = 2;
    foreach($new_data as $val){
        $currentSheet->setCellValue('A'.$j,$val['ID'])->setCellValue('B'.$j,$val['公司全称'])->setCellValue('C'.$j, $val['公司简称']);
        $j++; // 每循环一次换一行写入数据
    }
    $sheeetWrite = \PHPExcel_IOFactory::createWriter($excelObj, 'Excel2007');
    $sheeetWrite->save($dir.'设计公司名称.xlsx');
